Arguments

 

display-id

   OpenVMS usage:identifier
   type:         longword (unsigned)
   access:       read only
   mechanism:    by reference

   Display identifier of the virtual display with which the
   subprocess is associated. The display-id argument is the address
   of an unsigned longword containing this identifier.
 

command-desc

   OpenVMS usage:char_string
   type:         character string
   access:       read only
   mechanism:    by descriptor

   Command string. The command-desc argument is the address of a
   descriptor pointing to the command string.
 

flags

   OpenVMS usage:mask_longword
   type:         longword (unsigned)
   access:       read only
   mechanism:    by reference

   Optional bit mask that specifies optional behavior. The flags
   argument is the address of an unsigned longword that contains the
   flag. The valid values for flags are as follows:

   SMG$M_DATA_FOLLOWS   Input data follows. The next call to
                        SMG$EXECUTE_COMMAND contains input data
                        for the currently executing command. Do not
                        specify this value if this is the last input
                        data item. If you do specify this value,
                        ret-status is not returned.
   SMG$M_SEND_EOF       Send end-of-file marker. The end-of-file
                        marker is sent to the subprocess.
 

ret-status

   OpenVMS usage:cond_value
   type:         longword (unsigned)
   access:       write only
   mechanism:    by reference

   Optional status of the executed command, provided that the
   commands are not being buffered. The ret-status argument is the
   address of an unsigned longword containing this status.
